ICE-SCORING MAGHINE Application nl ed October 23, 1922. Y Serial No. 596,523.

To all whom t may concern.'

Be it known that I, EBENEZER BEDFORD,

a subject of t-he King of Great Britain, and resident of 102 Admiral Road, in the'city of Toronto of the Province of'Ontario, in the Dominion of Canada, halve invented certain new and useful Improvements in Ice- Scoring Machines, of which the following is the specification.

This invention appertains generally to the art of ice scoring machines and apparatus, as described in the present specification and illustrated in the accompanying drawings that form part' of the same.

The invention consists essentially of the novel features pointed out broadly and specifically in the claims for novelty following a description containing an explanation in detail of an acceptable form of vthe invention.

In order that the novelty and utility of my invention may be readily understood, I shall refer briefly to the structure and operation of well-known ice scoring machines. The ordinary method of scoring ice is'to feed the same by gravity from overhead intermediate rotary scoring saws, which are gauged to score the ice to the required depth. While this method of scoring ice has proven very satisfactory and may be used in ice-freezing plants of certain design, the same is not generally adapted for universal installation, due particularly to the' necessity. of the overhead feed.

With' the above mentioned undesirable. features of structure and operation in view, this invention provides means for lautomatically intermittently liftin yvertically arrangedfblocks of ice from o a oor or slide as they are delivered from the icefreezing plant; for canting the same over onto their sides and advancing the same' along a feeding slide to intermediate rotary' scoring saws; and for automatically delivering the same onto a. fioor or onto a slide upon completion of the scoring operation. The scoring mechanism, furthermore, is susceptible to adjustment to admit its application to different sized batches of blocks of ice. In addition, readily accessible means are provided for adjusting the relation of the scoring saws with respect to the blocks of ice fed therebetween so that the same may be scored to any required depth vto facilitate subsequent division into sections of predetermined size.

Supplementing the advantages aorded by the automatic feeding, scoring and delivering means, are those derived from utilizing readily accessible single score sco-ring mechanism, whereby the blocks may be scored for single division only.

From 'the viewpoint of universal adaptation, this invention marks a decided advancement in the art in that it may be installed in practically any design of ice scoring plant, irrespective of the plane on which the ice is delivered to the /scoring mechanism. As before premised, special means for this purpose have been devised and, combined with other instrumentalities of this invention, all of which will now be described in detail on reference to the accompanying drawings in whichzf- Fig. 1 is a side elevation of an ice scoring machine constructed in accordance with an acceptable embodiment of my invention, the position of the blocks of ice being depicted prior to, during,v and after the multiple scoring operationis;

Fig. 2 1s a similar view illustrating a'relative position of the scoring means 'for single scoring.

Fig. 3 is a transverse section of the `machine' as it would appear when taken on the" plane designated by the line 3-3 on Fig. 1.

Fig. 4 is a longitudinal section as it would appear when taken on the plane designated Fig. 5 isa horizontal section as it would appear when taken on the plane designated by the line 5-5 on Fig. 1.

VLike numerals ofreference designate. corresponding parts throughout the different views.

General construction.

The term floor as herein used, is inf tended to. include anyilat surface, slide, or the equivalent, upon which blocks of ice may be conveyed or transported to and from the ice scoring machine. vA very concise description of the Hoor upon which the 1ce scoring machine is mounted will suice, s1nce the particular ty e of such is immaterial to the invention wiiich has a .Winde range of utility irrespective of the speclc construction of the Hoor or slide upon which the blocks of ice are fed and delivered.

In the drawing is shown, for the purpose of illustration only, what is known as a concrete floor 6 in whichthe pit 7 is formed and in which the ice scoring machine is mounted, so that the blocks of ice to be scored? will not have to be elevated to any great extent for transition intermediate the scoring saws.

The main frame of the machine may be formed of four vertical standards 8, 9, 10 and 11, intermediate which are arranged longitudinal beams 12, 13, 14 and 15, and the transverse beams 16 and 17 all of which are securely fastened together by the plates 18 which are riveted thereto.

The scoring mechanism is carried upon an articulated frame designated in its entirety by the numeral 19, said frame being formed of vertical sections 2O and 21 and the transverse sections 22 and 23, all of which are secured together to form a rigid structure by the corner brackets 24 which are riveted thereto. This frame is articulated on the trunnions 25 and 26 carried thereby which are supported in bushings 27 and 28 mounted upon the longitudinal beams 12 and 13 of the main frame, so that the same may be swung backward or forward for multiple or single scoring, or for regulating the depth of the scores to be made, as will be hereinafter more clearly set forth.

The extent of adjustment of the frame 19 is determined by the length of the arcual slots 29 and 30, which are cut in the longitudinal beams 14 and 15 and have a radius taken from the centre of the trunnions 25 and 26. Bolts 31 and 32, carried by said frame 19, extend through said arcual slots 29 and 30 and are provided with locking nuts 33 and 34 by which said frame may be securely locked in any required4 position.

Shafts 35, 36, 37 and 38 are journalled in earings mounted upon said frame 19. Multiple scoring saws 39 are mounted in spaced relation on said shaft 35 in alignment with corresponding multiple scoring' saws 40, mounted upon the shaft 36, while single scoring saws 41 and 42 are mounted upon shafts 37 and 38 respectively.

The said saws are rotated by the electric motor 43 by the belt 44 trained over the pulley 45 mounted upon the motor shaft 46; over the pulle s 47 and 48 mountedupon the ends of the s pulley 49 mounted upon the shaft 50, which 1s journalled in bearings 51 and 52, mounted upon the longitudinal beams 14 and 15. The shafts 37 and 38 are rotated synchronously with the shafts 35 and 36 by the belts 53 and 54, which. are trained over the pulleys 55 and 56 and the pulleys 57 and 58 mounted upon the ends ef the said shafts.

The mechanism to pick up, feed and deafts 35 and 36, and over the 7 which is eected liver the blocks of ice includes the shafts 59 and 60, the former being journalled in adjustable bearings 61 and 62mounted in the guides 63 and 64, adjustment thereof being effected by the adjustment hand wheels 65 and 66; the latter shaft 60 being journalled in stationary bearings mounted upon the vertical standards 9 and 10.

Sprockets 67 and 68 are mounted upon the shaft 60 in spaced relation and in longitudinal alignment with the sprockets 69 and 70 mounted upon the shaft 59. Endless chains 71 and 72 are trained over said sprockets, as more clearly depicted in Fig. 2 and are provided with flights 71a and 72, which are used to propel the ice to undergo the scoring operation, during which it is advanced along a slide formed of channel se'ctions 73 and 74, and the angle sections 75 and 76, all of which are mounted upon the transverse beams 77 and 78, which are supported from the longitudinal beams 12 and 13 by the brackets 79.

The picking up, feeding and delivering mechanism briefly referred to, is drivenby the motor 43, through the shafts 50, 8,0, 81 and 60. Shaft 80 is driven by the shaft 50 at a reduced ratio through the medium of the belt 82 trained over the pulley 83 and the pulley wheel 84. The shaft 80 drives the shaft 81 at a correspondingly reduced ratio by the belt 85 trained over the pulleyv 86 and the pulley wheel 87, which is mounted upon the stub shaft 81, the latter being journalled in the bearings 88 and 89 mounted upon the vertical standard 9. The stub shaft 81 drives the shaft 60 through the medium of the pinion 90, which is keyed to the shaft 60. By this method of gearing, speed is further reduced so that the conveying mechanism will travel at the proper speed for picking up,l feeding andv delivering the blocks of ice.

The letters A designate the blocks of ice'to be fed 'as they are delivered from the freezing plant, the'same being picked up, canted over, and deposited upon the ice-feeding slide referred to, by the arms 92 and 93 carried by the shaft 59, the ice during the elevating operation bearing upon the supporting j wheels 94 and 95, which are of reater diameter than the sprockets 69 and 70, so that the ice will not come in contact with the same.

After the ice is deposited upon the feeding slide, the same is advanced by the flights 1 and 72a to undergo the scoring operation b the scoring saws referred to, after whlch the ice is delivered upon the supporting wheels 96 and 97 and is lowered by the arms98 and 99 carried by the shaft 60 on to the floor, as depicted by the letters (3, the blocks of ice during delivery being cantedv back to vertical position.

rThe frictional contact of the chains 71 and 72 with the chel sections 73 and 74, is re- General operation.

For single scoring, the articulated frame is adjusted as illust-rated in Fig. 2, that is to say,-the locking nuts 33 and 34 are to the right of the vertical axis of the trunnions 25 and 2G. The depth ot' the scores may he regulated as required, by regulating the inclination of the articulated frame either. to the right or to the left for a shallower or deeper score. lresuming that multiple scoring is desired, the articulated frame 19 is located in the approximate po- Isition shown in Fig. 1, after which l the motor 43 in energized, thus driving the ice scoring mechanism and the picking up, feeding and delivering mechanism.

The blocks of ice to be scored are fed from the left and are, for the purposes of illustration, designated by the letters .X. As they are fed, they are elevated by the arms' 92 and 9:3 from otf the Hoor G and are caused to cant over on their sides and bear upon the supporting wheels 94 and 95. due to the contour of said arms 92 and 93` which deposit a block of ice upon each revolution of they aaft 59 upon the feeding slide reft'rred' to. Each. block of ice. is advanced along the feeding slide on its side as shown in Fig. 1, and indicated by the letter B by the pairs of flights herein referred to, and upon completion of the scoring operation` is propelled forward and deposited upon the supporting wheels 96 and 97 and is canted over and lowered by the arms 98 and 99 on to the floor 6 at the right of the machine, as dep-icted by the letter C For single scoring, the articula-ted frame is adjusted to the position shown in Fig. 2, so that the single scoring saws 41 and 42 mounted upon the shafts 37 and 38, will be brought into the- -path of the advancing ice and the multiple scoring saws 39 .and 40 Will assume the positions shown. The blocks of ice.are picked up, fed and delivered in the manner previously described, for the single scoring operation.

Adjustment of the articulated frame from the position shown in Fig. 1 to the position shown in Fig. 2, necessitates adjustment of the motor 43, to the left, from substantially the position shown in Fig. 1 to substantially the position shown in Fig. 2, due to the fact that the belt 44 has one run forming the hypotenuse 35-46 of a right angle triangle of which the vlegs are the horizontal and vertical distances of the axis of 35 from that of 58, and another run forming the hypo-tenuse 36-48 of a right angle triangle. having as legs the horizontal and vertical distances of 36 and 46. The action ofthe swinging frame is to approximately increa-fe the horizontal leg of one triangle b v the same amount that.. the other di-l minished. hut on account of the difference of the vertical leg of one from that of the other. the h vpotenuses are slightly varied to secure a constant belt length. consequently it is necessary to adjust the motor to the left, as mentioned.

It will be observed that the vertical ribs of the channels 73 and 74 and the angle guides T5 and T6 will cut into the ice during its transition thereover and maintain the same in alignment. It will also be ohserved that the channels and angles forming the feeding slide are slightly inclined to the left of the beam 78 so that thev ice during the feeding operation must be propelled up the slight' incline. thus preventing it from slipping and impinging the scoring saws with velocity after its pick-up. The inclination ot' the feeding slide at4 the right of the beam 78 facilitates delivery of the ice in that it will readily slide off the feeding slide onto the supporting wheels 96 and 9T and the arms 98 and 99.

Vithout further analysis the. foregoing will so fully reveal the gist of` this invention that others can. by applying current knowledge, readily adapt it to various applications without omitting certain features that, from the standpoint. of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and therefore such adaptations should and are intended to be comprehended within the meaning and range of equivalency of ensuing claims.
